[texts]Method and apparatus for measurement of trap density and energy distribution in dielectric films - NON
Trap densities in dielectric films are determined by tunnel injection measurements when the film is incorporated in an insulated-gate field effect transistor. Under applied bias to the transistor gate, carriers (electrons or holes) tunnel into traps in the dielectric film. The resulting space charge tends to change channel conductance. By feeding back a signal from the source contact to the gate electrode, channel conductance is held constant, and by recording the gate voltage as a function of t...

[texts]THE EFFECT OF REPEATED RESTRICTIONS OF MOTOR ACTIVITY UPON SYSTOLIC BLOOD PRESSURE OF ALBINO RATS - POPPEI, M.
THE INFLUENCE OF REPEATED RESTRICTIONS OF MOTOR ACTIVITY ON SYSTOLIC BLOOD PRESSURE WAS EXAMINED FOR SEVEN AND A HALF MONTHS IN 54 MALE AND FEMALE ALBINO RATS. WITH INCREASING DURATION OF RESTRAINT, BLOOD PRESSURE READINGS FROM 114 TO 146 TORR WITH A HIGH OF 240 WERE OBTAINED. BLOOD PRESSURE REMAINED HIGH FOR FIVE WEEKS FOLLOWING THE EXPERIMENT, LEADING TO THE CONCLUSION THAT THE EFFECTS ARE CHRONIC.

[texts]Line narrowing of AgGaSe2 optical parametric oscillator by injection seeding - Watson, George H.
Solid-state lasers are developed for atmospheric applications. Optical parametric oscillators (OPO) are being investigated as sources of tunable radiation in the 2.5-12 micron range where development of conventional lasers is subject to numerous difficulties. Parametric oscillation is a nonlinear optical technique for converting laser output to longer wavelengths. Incident photons, typically from a pulsed pump laser, are converted into two photons of longer wavelength, while satisfying energy co...

[texts]Emittance Measurements for a Thin Liquid Sheet Flow - Englehart, Amy N.
The Liquid Sheet Radiator (LSR) is an external flow radiator that uses a triangular-shaped flowing liquid sheet as the radiating surface. It has potentially much lower mass than solid wall radiators such as pumped loop and heat pipe radiators, along with being nearly immune to micrometeoroid penetration. The LSR has an added advantage of simplicity. Surface tension causes a thin (100-300 microns) liquid sheet to coalesce to a point, causing the sheet flow to have a triangular shape...

A variety of techniques can now be used to alter the genome of a cell. Although these techniques are very powerful, they also have limitations related to cost and efficiency of scale. Artificial cells designed for specific applications combine properties of biological systems such as nano-scale efficiency, self-organization and adaptability at relatively low cost. Individual components needed for such structures have already been developed, and now the main challenge is to integrate them in func...

[texts]Analysis of the Hessian for Aerodynamic Optimization: Inviscid Flow - Arian, Eyal
In this paper we analyze inviscid aerodynamic shape optimization problems governed by the full potential and the Euler equations in two and three dimensions. The analysis indicates that minimization of pressure dependent cost functions results in Hessians whose eigenvalue distributions are identical for the full potential and the Euler equations. However the optimization problems in two and three dimensions are inherently different...

IN IRON ALLOYS THIS OCCURS BETWEEN 100 AND 300 K. THE THEORIES ARE MANIFOLD. APPARENTLY ALLOY SOFTENING CANNOT BE EXPLAINED BY ONE SINGLE MECHANISM. DEPENDING ON THE TYPE OF ALLOY, THE EASY NUCLEATION OF DOUBLE KINKS, SCAVENGING, AND THE RESULTING CHANGE IN DEFORMATION MECHANISM MAY BE RESPONSIBLE.

[texts]Quantum statistics of Raman scattering model with Stokes mode generation - Tanatar, Bilal
The model describing three coupled quantum oscillators with decay of Rayleigh mode into the Stokes and vibration (phonon) modes is examined. Due to the Manley-Rowe relations the problem of exact eigenvalues and eigenstates is reduced to the calculation of new orthogonal polynomials defined both by the difference and differential equations. The quantum statistical properties are examined in the case when initially: the Stokes mode is in the vacuum state; the Rayleigh mode is in the number state; ...
